** Description changed: + SRU Justification: + + [Impact] + + Upstream v6.18-rc1 commit 4405a214df146775338a1e6232701a29024b82e1 + "ACPI: scan: Add Intel CVS ACPI HIDs to acpi_ignore_dep_ids[]" (also + backported to v6.17.8, v6.12.58), which in effect reverts a not yet + upstreamed Intel MIPI camera patch titled "ACPI: scan: Update HID for + new platform" meant for bug 2090932, and therefore they share the same + symptom: + + [ 4.484426] ov02c10 i2c-OVTI02C1:00: chip id mismatch: 560243!=0 + [ 4.484432] ov02c10 i2c-OVTI02C1:00: failed to find sensor: -6 + + [Fix] + + While this should really be fixed by upstream Intel's CVS driver and + remove the two platforms from acpi_ignore_dep_ids, a sauced change is + made to preserve the honor effect and yet don't introduce potential + conflict with the upstream before any further progress is made. + + [Test Plan] + + 1. Install the kernel from -proposed pocket and reboot into it. + + 2. Check dmesg has no aforementioned error, + + 3. Make sure the device appears in the gstreamer device enumeration: + + $ gst-inspect-1.0 icamerasrc + ..... + device-name : The input devices name queried from HAL + flags: readable, writable + Enum "GstCamerasrcDeviceName" Default: 0, "ov02c10-uf" + (0): ov02c10-uf - ov02c10 as sensor. + + [Where problems could occur] + + No. This restores the hardware enablement effort for the affected + platforms only. For Ubuntu, CVS driver is always available along with + the kernel, and therefore for a device declared _DEP to the two ACPI + devices, the driver can be installed either through ubuntu-drivers or + through oem meta packages. + + [Other Info] + + While this has been backported to v6.17.8, it affects R and Q. And while + this has also been backported to v6.12.58, and linux-6.8/noble is + tracking stable 6.8 fixes, Noble will be affected soon or later. + Nominate for N, Q and R accordingly. + + ========== original bug report ========== + [Summary] During the kernel SRU testing, we found out that 3 xps13-9350 camera-related tests failed. I saw following in dmesg. ov02c10 i2c-OVTI02C1:00: failed to find sensor: -6 - [Reproduce steps] 1. Install GM image 2. Run dist-upgrade to upgrade to 6.17-oem kerenl 3.
